For the left side of the body, the common carotid and subclavian arteries arise directly from the?

a. aorta

Which of the following is the larger terminal branch of the external carotid artery?

d. maxillary

The brachiocephalic veins unite to form the

d. superior vena cava

Which of the following structures are contained within the carotic sheath?

b. internal jugular vein

1. Within the vascular system, a large network of blood vessels is a?

plexus

A large network of blood vessels is a plexus within the vascular system.

2. What are blood-filled spaces between two layers of tissue in the vascular system?

A) Venous sinuses

Venous sinuses are blood-filled spaces between two layers of tissue in the vascular system.

3.What within the vascular system is smaller than an arteriole and can supply blood to a larger tissue area because there are so many of them?

D) Capillary

The capillary is smaller than an arteriole and can supply blood to a larger tissue area only because there are so many of them within the vascular system.

4.What can be felt if the anterior border of the sternocleidomastoid muscle is rolled posteriorly at the level of the thyroid cartilage of the larynx or "Adam's apple," producing a groove of tissue?

E) Carotid pulse

If the anterior border of the sternocleidomastoid muscle is rolled posteriorly at the level of the thyroid cartilage of the larynx or "Adam's apple," the carotid pulse can be felt in the groove of tissue produced.

5.Which of the following travels to the heart and caries blood?

A) Vein

A vein, unlike an artery or capillary, arteriole, or venous sinus, travels to the heart and carries blood.

6.What is MOSTLY absent in the vascular system of the head and neck area, unlike in the rest of body?

D) Valves in the veins

Valves in the veins are mostly absent in the head and neck area, unlike in the rest of the body.

7.In most cases what drains the capillaries of a tissue area within the vascular system?

C) Venule

After each smaller vein or venule drains the capillaries of the tissue area, the venules coalesce to become larger veins.

8.What can cause narrowing and blockage of the arteries leading to pathologic changes?

D) Fatty plaque

The narrowing and blockage of the arteries can cause pathologic changes, which can be by a buildup of fatty plaque.

9. Within the vascular system, what is a clot that forms on the inner vessel wall?

E) Thrombus

A clot(s) or thrombus (plural, thrombi) that form(s) on the inner vessel wall within the vascular system.

10.When a blood vessel is seriously traumatized, large amounts of blood can escape into surrounding tissue without clotting, causing a

A) hemorrhage.

When a blood vessel is seriously traumatized, large amounts of blood can escape into surrounding tissue without clotting, causing a hemorrhage.

11.Which of the following is an EXCELLENT example of variability within the vascular system?

B) Lingual veins

One excellent example of the venous variability concerns the lingual veins, which include the dorsal lingual veins that drain the dorsal surface of the tongue, the highly visible deeper lingual veins that drain the ventral surface of the tongue, and the sublingual veins that drain the floor of the mouth.

12.Which artery is hidden by the coverage of the large sternocleidomastoid muscle of the neck?

B) Internal carotid artery

The internal carotid artery is hidden by the coverage of the large sternocleidomastoid muscle of the neck.

13. Besides the common carotid arteries, which of the following area major arteries directly supply the head and neck?

B) Subclavian arteries

The major arteries that supply the head and neck include the common carotid and subclavian arteries.

14. Just before the common carotid artery bifurcates into the internal and external carotid arteries, it exhibits the

B) carotid sinus

Just before the common carotid artery bifurcates into the internal and external carotid arteries, it exhibits a swelling, the carotid sinus.

15. Blood vessels within the vascular system communicate with each other by

B) anastomoses.

Blood vessels in the vascular system may communicate with each other by an anastomosis (plural, anastomoses), a connecting channel(s) among the vessels.

Anastomosis

Communication of blood vessels, with one another blood vessels by connecting channels

Arteriole

Smaller artery that branches off an artery and connects with a capillary

Artery

Type of blood vessel that carries blood AWAY from the heart

Atherosclerosis

Narrowing and blockage of the arteries by buildup of fatty plaque.

Bacteremia

Bacteria traveling within the vascular system.

Capillary

Small blood vessel that branches off arteriole to supply blood directly to tissue

Carotid pulse

Reliable pulse palpated from the common carotid artery.

Embolus

Foreign material such as thrombus traveling in the blood that can block the vessel.

Hematoma

Bruise Results when a blood vessel is injured and a small amount of blood escapes into surrounding tissue and clots.

Hemorrhage

Large amounts of blood that escape into surrounding tissue without clotting when a blood vessel is seriously injured.

Plaque

Substance which consists of cholesterol mainly, and calcium, clotting proteins and other substances that can be found in the lining of the arteries.

Plexus

Network of blood vessels, usually veins

Thrombus

Clots that forms on the inner blood vessel wall.

Vascular system

System that consists of an arterial blood supply, a capillary network, and venous drainage.

Vein

Type of blood vessel that travels to the heart, carrying blood.

Venous Sinuses

Blood filled space between two layers of tissue

Venule

Smaller vein that drains the capillaries of the tissue area and then joins larger veins

Brachiocephalic artery

Artery branching directly off aorta on right side of the body giving rise to the right common carotid and subclavian arteries

Subclavian artery

Artery arising from the aorta on LEFT and Brachiocephalic artery on the right and giving rise to branches to supply both interacrainal and extracranial structures, as well as the arm.
